| Abstract: | This article introduces a new method to measurement the activity of radioxenon isotopes. The plastic tube-type gas cell and samples transfer apparatus were researched and manufactured. Peak efficiency of well-type HPGe detector was calibrated with the archive sample of CTBT noble gas exercise. The minimum detectable activity reaches 10.2 mBq to 81 keV gamma ray of ~(133)Xe in 24 h measurement time. |
